The distribution of laser beams' intensity leads to such important spatial parameters as oscillation modes of laser device, divergence Angle of laser beams, the power of laser beams, laser radius etc.
A beam of high radiant power will have high divergence.
高辐射功率的光束会有高的发散度。

The output parameters such as beam divergence angle in far-field output power of high power solid state lasers are variable due to thermal effect of optical pumping.
